Extraction of ASO from spent sulfuric acid using liquid SO2 |
摘要 |
A process for the regeneration of spent sulfuric acid including contacting spent sulfuric acid containing acid soluble oils (ASO) with sulfur dioxide to extract at least a portion of the ASO from the spent sulfuric acid into the sulfur dioxide. The sulfuric acid phase having a reduced ASO content and a sulfur dioxide phase containing at least a portion of the ASO may be recovered. The resulting sulfuric acid and sulfur dioxide phases may be further separated to recover ASO, sulfur dioxide, and sulfuric acid.
